Azuo Lee updated OPENJPA-2377:
------------------------------
Description:
I use the following code to dynamically determine if a class is an embeddable:
Class c = Class.forName(s);
ManagedType type = metamodel.managedType(c);
if (type.getPersistenceType() == Type.PersistenceType.EMBEDDABLE) {
logger.debug("" + c + " is an Embeddable.");
// do somthing with the embeddable
}
else if (type.getPersistenceType() == Type.PersistenceType.ENTITY) {
logger.debug("" + c + " is an Entity.");
// do somthing with the entity
}
}
but when I use this code for an Embeddable, I always get "xxx is an Entity"
logged.
After examining the source code, I found "MetamodelImpl.instantiate" method
will always put embeddable to both "embeddables" and "entities" containers, but
"MetamodelImpl.managedType" method will first search "entities" and then
"embeddables" for a persistence class, thus, "Entity" type will be returned for
a ACTUAL Embeddable class.
Hope this can be fixed.
